    Dandelion Energy CEO Dan Yates On How Geothermal Leasing Could Transform Home Heating and Cooling

    Read a transcript of this interview.

    Amazingly, the same Congressional bill that gutted residential clean energy tax credits also led to a major breakthrough in financing home geothermal systems. Dan Yates, CEO of Dandelion Energy, explains how the Big, Beautiful Bill introduced changes that, for the first time, allow third-party leasing of residential geothermal systems. He shares why this policy change could help ground-source heat pumps grow the way leasing helped rooftop solar. Geothermal heating and cooling is four times more efficient than a furnace and twice as efficient as air-source heat pumps. Yet only about 1% of U.S. homes use it because the upfront costs for new geothermal systems have ranged from $20,000 to $31,000. The new leasing model means new homeowners can get geothermal systems for just $10 to $40 per month on a 20-year lease, which is usually far less than what they save on energy.

    Dandelion is working with Lennar, one of the largest homebuilders in the country, to bring geothermal to more than 1,500 homes in Colorado over the next two years. This will be one of the biggest residential geothermal projects in U.S. history. The benefits for the power grid could be even more important than the savings for homeowners. Geothermal systems use only 25% of the peak power that air-source heat pumps need, which is a big advantage as AI data centers increase electricity demand. Yates explains that the Earth works like a huge thermal battery, storing heat in the summer for use in the winter. Geothermal lets utilities reduce peak loads on the grid throughout the year, freeing homeowners from the cost of the most expensive power.

    The ocean provides half the oxygen we breathe, absorbs 30% of our carbon emissions, and helps control the planet's climate. By 2030, it's expected to support a $3.2 trillion Blue Economy. Yet 70% of proven ocean solutions, such as coastal resilience, coral restoration, and marine pollution cleanup, never move past the pilot stage. These projects often win awards and get media attention, but then stall because funding systems don't connect working ideas with the cities, ports, and coastal areas that need them. Stewart Sarkozy-Banoczy, co-founder and ocean lead at Okhtapus, wants to change that. Okhtapus, named with the Persian word for the octopus, uses a model that links what Stewart calls "the three hearts" of successful projects: innovators with proven solutions, cities and ports ready to use them, and funders looking for solid projects.

    The first Okhtapus Global Replicator will launch in 2026. It will bring groups of proven innovators to work on important projects in specific places, such as a single port city like Barcelona, where Okhtapus already has strong partnerships, or a group of Caribbean islands facing similar problems. The aim is to have enough successful projects that funders stop asking "where are the deals?" and start saying "we've got enough." The platform focuses on late-stage startups and scale-ups, not early-stage ideas. Stewart calls these the "Goldilocks zone"—solutions that are proven enough to copy but still need funding and partners to grow. By combining several solutions for different locations, Okhtapus can offer investors portfolios that fit their needs and make a real difference in cities, ports, and island nations.

    Stewart has spent twenty years working where climate resilience and policy meet. He was part of President Obama's Hurricane Sandy Rebuilding Task Force, led policy and investments at the Resilient Cities Network, and is now Managing Director of the World Ocean Council. "Ten years from now, if this is done fast enough," Stewart said, "we should have pushed hard enough on the funders and the system to change it. What we don't know is whether we'll get to the solution status fast enough for some of these tipping points."

  • EarthX CEO Peter Simek on Cultivating Bipartisan Climate Strategies

    EarthX CEO Peter Simek on Cultivating Bipartisan Climate Strategies

    For 15 years, the Dallas-based climate conference the EarthX conference has created space where fossil fuel executives and environmental activists, Republican appropriations chairs and Democratic climate hawks, find common ground. The organization targets three core stakeholders: the corporate world, policymakers, and investors seeking startups where environmental solutions are baked into the bottom line. Peter Simek, EarthX’s CEO, explains how reframing climate action around shared values—stewardship, economic opportunity, and love of the land—unlocks support that crisis messaging alone cannot reach.

    The doom story doesn’t sell, Simek explained. “We’re not motivated as a species by doomsday language. It puts people in fight-or-flight mode.” He points out how climate became an identity issue, tangled up in culture-war debates over hamburgers and gas-powered trucks, when the real conversation should center on clean air, clean water, and protecting the places we love. “The EPA and the Clean Air and Clean Water Act were passed during the Nixon administration,” he notes. “There are ways to message this that appeals across lines.”

    Simek bets heavily on bottom-up action as EarthX works to build bridges. States, cities, and private capital often move faster than federal mandates, he argues, and they’re harder to reverse with a single executive order. Texas leads the nation in renewable energy deployment because wind and solar make bottom-line sense. “Even as there’s a policy turn against it, there’s still the driving reality that solar and wind are viable energy sources,” he says. A new event in 2026, the EarthX Institute, will focus on two policy priorities: nuclear energy, where bipartisan consensus is growing, and urban biodiversity.

    Whether conversations at forums like EarthX translate into policy velocity that matches the pace of climate impacts remains to be seen. Simek says he stays focused on tracking downstream results, specifically the investments funded, the coalitions built, and the policies incubated from the local level up. “It’s about finding those ways in which there’s common sense, common ground, common values,” he says. “Elements to talking about nature and the environment that no one can really disagree with.”
